Title: Improvements in or relating to metal structural members
IPC: A47B96/14
Filed: 1936-05-16
Abstract: 476,867. Composite structural members. HENDERSON, A. May 16, 1936, No. 13945. [Class 20 (ii)] Composite beams and like structural members are formed from angle-bars with perforated flanges and connecting plates which form the webs of the beams, the connecting plates having rows of spaced apertures of the same spacing as those in the angle-bars, the distances between the rows also being integral multiples of the aperture spacing, so that the elements may be variably joined to form openwork beams of different depths and sizes. The angle-bar 10, Fig. 2, is shown having perforated flanges, and rectangular connecting plates 13, Fig. 3, with rows of holes 14 of similar pitch, and the distances between the rows integral multiples of this pitch, so that the angle-bars may be joined by the plates to form various depths of openwork girders. Figs. 6 and 8 show two forms of girder of different depths formed by reversing the connecting plates. Larger rectangular connecting plates with similarly pitched holes and rows give a further range of adjustment for depth. The apertures 32, Fig. 17, may be positioned in each flange of an anglebar 31 a distance inwardly from the edge equal to the pitch, and the connecting plates 30 for use with these angle-bars are provided with multiple rows of apertures, so that they may connect the angle-bars in various ways, as shown, for example, in Figs. 20 and 26. Beams 53 may be connected to columns 50 directly, as shown for example in Fig. 39, or alternatively, the end connecting plate 34 of a beam may be connected to a projecting connecting plate of a column, as shown for example in Fig. 32, the column being strengthened at the base by additional angles 35, the upper ends of which abut under the beams ; short angle-pieces 37 are used to connect the column to its support 36. Various alternative arrangements for connecting beams to columns and for connecting column extensions to their main portions are shown and described.

Abstract: 1,075,641. Manipulators. RANK ORGANIZATION Ltd. Aug. 10, 1964 [Aug. 8, 1963], No. 13980/63. Heading B4Q. A manipulator for manipulating a piezoelectric ultrasonic probe 10 to enable the probe to be moved about three intersecting mutually perpendicular axes X-X, Y-Y, Z-Z, the axis X-X being perpendicular to the plane of Fig. 1 at the point of intersection of the other two axes, comprises a fork 12 in which the probe 10 is pivoted on a shaft 72 coincident with the axis X-X, this fork being journalled in a head 14 bodily rotatable about the axis Y-Y and carried in an angularly immovable frame 16. The drive for rotating the probe about axis Z-Z is taken from a drum 18 having a knurled rim 19 by a metal tape 20 passing over idler drums 22, 23 to a drum 24 on a countershaft 26 bearing a second drum 28. From the drum 28 a tape 30 passes over an idler 31 to a drum 32 on the fork 12. The degree of rotation about the axis Z-Z is read from a scale 34 against a zero mark 36. Rotation about the X-X axis is effected by a tape drive from the lower end of a shaft 38 to the upper end of which is secured a knurled manipulating drum 40 having a scale 42 of angular position reading against a zero mark 44. The drive comprises a tape 46 around the shaft 38 and passing over a drum 54 on a countershaft 50, a tape 52 from the drum 54 to a drum 56 on a countershaft 58, a tape 60 from a drum 62 on a countershaft 58 within the hollow arm of the fork 12 to a drum on a countershaft 64, and from a drum 66 on that shaft by a tape 68 to a drum 70 on the shaft 72. Rotation about the Y-Y axis is effected by a knurled drum 74 in the upper end of a shaft 76 journalled in a housing 78 rigid with the frame 16. In order that the X-Y relationship is not disturbed when the drum 74 is rotated there is a friction plate 80 and a bearing bush 82 between the drum 40 and a metal sleeve 84 fixed within the shaft 76. The zero mark 44 is carried by the drum 74. In order that rotation of knob 40 shall not cause unwanted rotation of shaft 76 the latter is journalled in the housing 78 with a friction plate 90 between the drum 74 and the housing. In use the manipulator is mounted on a carriage (not shown) for translational movement in three dimensions.

Abstract: 1,038,512. Axial-flow fans. A. G. BORCHERS. April 9, 1963 [April 16, 1962], No. 14082/63. Heading F1C. [Also in Division B7] An axial-flow fan for ventilation, running at a predetermined speed has its blades shaped to provide a vortex stream generating a centrifugal force at its periphery which provides that the radial pressure of the discharged air will equal approximately the static pressure of the ambient fluid into which the air is discharged. The vortex is thereby projected from the fan as a rotating stream having a diameter substantially equal to the diameter of the fan. The rotational velocity at the design radius produces a pressure rise thereat which is equal to half the static pressure drop at the entrance to the fan. In a fan having an outer diameter of 23 inches and a hub diameter of 4 inches, the inlet angles of each blade with respect to the rotational plane are 14À14 degrees at the tip, 19À6 degrees at the design radius (8À13 inches) and 55À35 degrees at the hub. The outlet angles are 16-6 degrees at the tip, 22À25 degrees at the design radius and 59À75 degrees at the hub.

Title: Improvements in television transmitters
IPC: H04N5/38
Filed: 1940-09-30
Abstract: 543,474. Television transmitters ; wireless transmitting systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Sept. 30, 1940, No. 14752. Convention date, Sept. 30, 1939. [Classes 40 (iii) and 40 (v)] In a television transmitter in which the synchronizing signals 11, Fig. 3, are combined with picture signals 13 to extend beyond black level 12 in the white to black direction, and the carrier wave is modulated negatively with the combined signal, the output of the final radio frequency amplifier stage is brought to or beyond its maximum continuous rating by the synchronizing signals, and the output may be automatically reduced if the carrier becomes unmodulated. As shown in Fig. 1, the combined picture and synchronizing signal coming from a terminal equipment 10 which may be as described in Specification 395,499 or 448,065, is fed through amplifier valves 16, 17 and by a direct current re-inserting diode circuit 27 which may be as described in Specifications 422,906 and 422,914 to a modulator valve 18 also fed with a carrier from a source 21. The modulated carrier passes from valve 18 to a push-pull power amplifier 19 by a direct coupling which may be as described in Specification 462,530 but for the sake of simplicity is shown as a battery 26. In addition the combined picture and synchronizing signal is supplied to a valve relay device 31, which holds contacts 43 closed so long as at least the periodic synchronizing pulses affect the valve. The contacts 43 when thus closed short circuit the right-hand section of a voltage divider 44 causing the bias applied to valve 18 to produce full loading of the amplifier 19. If the signal from the device 10 ceases, the valve relay 31 opens the contacts 43 and the negative bias applied by the voltage divider 44 to the valve 18 is therefore reduced, whereby the carrier amplitude output of the amplifier 19 is reduced to a safe value such as the amplitude representing black.

Title: Improvements in demountable x-ray tube construction
IPC: H01J35/26
Filed: 1953-05-27
Abstract: 726,021. X-ray tubes. HORIZONS, Inc. May 27, 1953 [June 3, 1952], No. 14777/53. Class 39 (1). An X-ray tube has a rotary anode 19 which is cooled by circulation of water in the interior thereof, said anode being supported on a frame forming part of the side wall of the tube envelope, the anode driving mechanism being mounted on the same frame. The anode-supporting frame 6 also serves as a cover plate to the main tube envelope 5, with a soft sealing gasket 10. Eccentrically disposed on frame 6 is an inwardly extending annular part 11 carrying two rings 12 and 12'. Parts 11, 12 and 12' bear through greased sealing rings 13 against sleeve 15, which has an integral flange 17 at one end, and a threaded flange 16 at the other. The anode proper is a cylindrical drum 20, 21, 22, 23, 24, carried by an integral support sleeve 25. On the lower end of sleeve 25 is screwed a driving cap 26, which can be tightened so as to compress a rubber sealing gasket 28 between flange 16 and the part 24 of the anode. The rotating anode is driven from a pulley 34 and a gear train 30, 31, all mounted directly on the frame 6, the gears engaging with the driving cap 26. The water connections are provided by a stationary union consisting ot a sleeve 39 with a tube 40 inside it. The cooling water enters through line 37, circulates inside the anode drum, and discharges through line 38. A packing gland 45 forms a water seal between the sleeve 39 and the stationary parts. The design is suitable for a demountable tube; anode shells 20 of different materials may be used for obtaining different X-ray characteristics, or the shell may comprise segments of different metals. A further feature is that the anode drive, and water supply lines, are all well clear of the peripheral windows 36.
